Regarding Faith vs Kakistos (from Bloodstone's Boss FAQ):
Before going into the battle with Kakistos, you'll get 2 medi-paks. It's also wise to have at least one more just in case.
After the cut scene, immediately start running around. The glowing orbs surrounding in the outer areas all must be destroyed before fighting Kakistos. Any damage you do to him, the orbs will just recover for him, so get rid of these.
You'll also have zombies rising from the ground, but these are no problem. Kakistos will also throw hellfire at you, making this fight even tougher. Start the fight by running the edges of the
area, hitting the orbs as you go, but don't stop running just yet.
It's best to do a jumping kick as you pass an orb. Like before, the orbs won't take any damage unless dim, but still, just hit them as you pass, just in case they do happen to go dim.
Kakisto's hellfires will be thrown in front of you, in an attempt for you to run into them. If you hear the sound of him throwing it, stop moving for the second it takes it to miss, or turn in the opposite direction and let it miss, then continue in your original direction.
He usually throws around two to four hellfires at a time, so when you see the first hellfire, be ready for more, and you should be able to avoid these.
After running in one giant circle over and over, Kakistos and the zombies will eventually follow you (note that Kakistos isn't as dumb as the zombies, and will sometimes break out of the following pattern).
When you're a good enough distance ahead of them, get on the backside of an orb and begin an all out attack on it. I say to get on the backside, because Kakistos could throw hellfires, and this will make the orb suck up most of the damage from it.
If the zombies get too close, you can waste them if you want, more will just come, but my advice would be to not waste the time unless you get low on energy and are out of medi-pak's, then maybe they can restore a small amount. If Kakistos gets close, start running again.
After all the orbs are gone, Kakistos should be no problem. Attack him head on, and bring his energy down. He fights like the other vamps, and since he is a vampire, you'll need to stake him to finish him off. I haven't tried it, but hellfire and holy water may also work to finish him, since he is a vampire.
Hope that helped.
) but the PS2 has more games.
- the combination can make for a very entertaining and bloodthirsty time, though I imagine it would get boring to play it that way all the time... 

I think I need help......
Big Zelda and Baldur's Gate fan also. I'm trying to finish the latter as we speak, damn giant spiders(ugh!)
